Description

BP-4 is a glycidyl methacrylate modified Poly(butylene succinate) withhigh grafting rate.

BP-4, as a glycidyl methacrylate modified Poly(butylene succinate), can be used as a coupling agent between biodegradable materials like polylactic acid (PLA), polybutylene succinate (PBS), and the infill materials which contain starch, wood powder, and others.

Characterisitic

BP-4 is a glycidyl methacrylate modified Poly(butylene succinate) withhigh grafting rate.

As a coupling agent, BP-4 can improve the interfacial adhesion between the biodegradable materials and the infill materials, leading to improved mechanical properties such as tensile strength, impact strength, and flexural strength. Additionally, the use of BP-4 can also improve the thermal properties of the composite material.

The addition of starch or wood powder to the biodegradable material can often reduce the mechanical properties of the composite, which makes the use of coupling agents like BP-4 necessary. The modified BP-4 can react with the hydroxyl groups on the surface of the starch or wood powder, forming chemical bonds that improve the compatibility between the biodegradable material and the infill material.

Overall, the use of BP-4 as a coupling agent between biodegradable materials and infill materials can lead to improved mechanical and thermal properties of the composite, making it a promising material for use in a range of applications, such as in the production of biodegradable packaging materials, automotive parts, and construction materials.
